I have no dog in this hunt, but I do know from experience that travel teams using rec field space can be a touchy subject. Field space for travel teams is in-demand and expensive; teams compete for quality space just like they do for good coaches and players. Rec teams are non-profits and work under a different set of rules. If a for-profit travel team is partnering with a rec program to use county fields under the rec permits, that could end badly for one or both of them.
Having said that, it is interesting that these two people (pro and con) are so emotional and adamant about the issue.
